Title: A method for cleaning gas mixtures which might contain dust from a urea plant
IPC: B01D53/34
Filed: 1982-12-23
Granted: 1986-02-26
Abstract: Gas mixtures from a urea plant, particularly such mixtures containing dust and especially off-gases from prilling towers or granulation units are cleaned. In order to prevent precipitation and accretion in the cleaning unit, there is applied an aqueous washing solution to which formaldehyde is added before it is brought in contact with the gas mixture. Formaldehyde is preferably added in the form of formaline, and the addition of formaline is regulated by pH-measurements in the washing solution such that pH is maintained at pH=6-8.5. The pH of the washing solution is preferably kept at pH=about 7, especially in order to obtain optimal removal of ammonia. The method is carried out during application of standard scrubbers in which aqueous washing solutions can be used.

Abstract: Electro-optic color control apparatus which is adapted for use in an electronic color imaging apparatus of the type having an array of electrically-addressable pixel light valves, each operating in the quadratic Kerr cell mode for selectively controlling the passage of light to different pixel regions of an imaging zone in response to informations signals. Such color control apparatus includes a panel (11) of electrically addressable color modulators which respectively control the passage of one of a plurality of light colors (e.g. red, green or blue) to an image plane, and circuitry (30, 35) for selectively addressing the color modulators in a predetermined sequence and for a predetermined time interval so that the color of light which reaches the image plane is coordinated with the color image information passed by the light valve array. Each color modulator comprises, in optical alignment, a pair of crossed polarizers (13, 14) having a color filter (R, G, or B) and an electro-optic light-modulating material (E) positioned therebetween. Material (E) is of the type which is adapted to rotate the plane of polarized light incident thereon in response to an applied electric field. The color control apparatus of the invention is particularly advantageous from the standpoint that it is readily synchronized with the electronic color imaging apparatus in which it is used, and it provides exceptionally short and well-defined pulses of colored light.

Abstract: An exhaust air valve for placement in a ventilation conduit through which air is exhausted from a space to be ventilated. The valve has a casing with a concave seat surface facing upstream of the flow through the conduit and having a central valve orifice. A convex valve element cooperates with the seat surface and when the valve is closed engages the seat surface along a line of contact surrounding the seat. The curvature of the respective surfaces is the same, at least along the line of contact to ensure a tight closure of the orifice by the valve body. When opening, the valve body slides along the curved surface and the upstream surface of the valve body exposed to the flow is also convex to guide the flow toward the center of the orifice. Several embodiments are illustrated including valves with cords for remotely controlling the valve and heat-sensitive tripping mechanisms which automatically close the valve in the event of a rise in temperature above a preset level. The closing movement may be pivotal about a pivotal connection maintaining the valve element in sliding contact with the valve seat or may be a sliding displacement longitudinally of a slot in one of the elements.

Abstract: Method and means for evaluating the quality of audio and/or video transfer characteristics of a device upon which, or through which, audio and/or video information is contained, or passes, respectively. Both method and apparatus concern the evaluation of the quality of information transfer in the recording and playing back of a recording medium or in the transferring of audio and/or video information through an information handling device referred to as a throughput device. Unit evaluation is accomplished by establishing an input signal of known content, measuring selected parameters of selected parts of the input signal, feeding the input signal to the unit under test, measuring the parameters of parts of the output signal from the unit under test corresponding to the same selected parts of the input signal, and comparing the selected parameters of the input signal with the corresponding parameters of the output signal. Whether monitoring the quality of the signal transfer characteristics of a throughput device, a magnetic tape containing program material, or a video disc, master disc or replica, a "siganture" is created for the unit under test, and subsequent analysis of the unit as it progresses along a production line or of a copy made on the same or alternate recording medium results in a second "signature" which is compared against the first signature to make a determination as to the quality of the signal handling or transfer characteristics of the unit. In this manner, out-of-tolerance conditions can be automatically detected, thereby eliminating subjectivity and providing consistency in the quality level of device testing.

The spring element is supported within a stop sleeve located within the housing and the stop sleeve is axially displaceable relative to the housing. A depth stop on the drive spindle is adjustable relative to the stop sleeve. An actuating sleeve accessible on the exterior of the screw driving device affords the adjustment of the stop sleeve and the depth stop. A connecting element is secured to the actuating sleeve and is in engagement with the depth stop so that the actuating sleeve and depth stop can be rotated as a unit. The connecting element is selectively engageable with the stop sleeve so that the actuating sleeve and stop sleeve can be rotated as a unit for adjusting the torque-limiting coupling.
